Description

Technical Field

[0001] The present invention relates to the field of water sterilization, in particular to a tap water ultraviolet sterilization device. Background Art

[0002] Ultraviolet sterilization technology has related applications in water purification. For example, ultraviolet lamps are used to irradiate water, and the high radiation characteristics of the ultraviolet C band are combined to destroy the nucleic acid structure of microorganisms in the water to achieve a strong sterilization effect on the water.

[0003] Based on experience, the ways of irradiating water with ultraviolet lamps include air irradiation or water irradiation. In the former, personnel can freely control the lamp group, such as wiping the lamp group to ensure the intensity of light penetration, etc. In the latter, light loss can be significantly reduced, and the sterilization effect is better. Of course, air irradiation and water irradiation also have corresponding disadvantages. For example, air irradiation often requires the use of high-power lamp groups, and water irradiation, because it is underwater for a long time and is mostly in a relatively closed environment, combined with water erosion, the light transmittance of the lamp group actually tends to decrease. Therefore, it is very necessary to provide a tap water ultraviolet sterilization device combining the advantages and disadvantages of air irradiation and water irradiation. Summary of the Invention

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0030] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0031] Example 1

[0032] In this embodiment, a tap water ultraviolet sterilization device is proposed. The sleeve cup 11 is provided with a cup cavity and a plurality of light rod cavities arranged around the cup cavity at the sleeve cup 11 .

[0033] Accordingly, along the arrangement direction of the lamp rod cavity, the ultraviolet lamp rod 3 is inserted into the lamp rod cavity to slide with the sleeve cup 11 ; in addition, the shunt tube is inserted into the cup cavity to slide with the sleeve cup 11 .

[0034] To further explain, in this example, the diverter tube includes a first tube 1 and a second tube 8 combined with the first tube 1 to form a straight tube, wherein a base 10 is provided at the bottom of the second tube 8 (the base 10 is a fixing part of the ultraviolet lamp rod 3, and is used to make the ultraviolet lamp rod 3 and the diverter tube move relative to the sleeve cup 11 when the diverter tube diverts water). Accordingly, the second tube 8 is limited to one port combined with the first tube 1. In addition, a plurality of diverter holes 14 are arranged in an array on the second tube 8, and each diverter hole 14 is directly facing the ultraviolet lamp rod 3 when exposed to the outside, so that when the diverter tube extends outward from the cup cavity, the water discharged from the diverter hole 14 directly hits the ultraviolet lamp rod 3 and flows along the shape of the ultraviolet lamp rod 3.

[0035] Of course, the combination of the shunt tube and the sleeve cup 11 requires corresponding components to be connected. For this purpose, a spring 7 is provided. The ends of the spring 7 are respectively fixed to the sleeve cup 11 and the base 10. This connection method, first of all, integrates the shunt tube and the sleeve cup 11 into one place. In addition, when the shunt tube slides relative to the sleeve cup 11, the spring 7 accumulates or releases kinetic energy. Specifically, it is described in combination with an example:

[0036] ① Water enters the first tube 1, and the water directly hits the base 10, generating a thrust (the thrust is greater than the combined pulling force provided by the multiple springs 7), causing the combination of the first tube 1 and the second tube 8 to extend outward relative to the sleeve cup 11. After extension, considering multiple variables such as water pressure, a diversion hole 14 corresponding to the variable is configured. The diversion hole 14 diverts the water and the diverted water impacts the ultraviolet lamp rod 3 in a straight line or parabolic manner, and the ultraviolet lamp rod 3 sterilizes the water.

[0037] ② After the water in the first tube 1 is reduced to zero, the spring 7 pulls the base 10 (the thrust is less than the combined pulling force provided by the multiple springs 7), forcing the combination of the first tube 1 and the second tube 8 to return to the sleeve cup 11, thereby pushing the UV lamp stick 3 back into the lamp stick cavity.

[0038] Combined with explanations ① and ②, the ultraviolet lamp stick 3 is limited to extending relative to the lamp stick cavity when water enters the shunt tube. In addition, the ultraviolet lamp stick 3 is in direct contact with water when extending (water impacts the ultraviolet lamp stick 3 and flows along the shape of the ultraviolet lamp stick 3, thereby extending the irradiation time). Therefore, it inherits the advantages of air-to-air irradiation and water-to-water irradiation. In addition, the ultraviolet lamp stick 3 is not actually immersed in water for a long time. In addition, when the ultraviolet lamp stick 3 moves relative to the sleeve cup 11, it contacts the sleeve cup 11 to carry out corresponding cleaning activities. Therefore, there is no need for personnel to maintain the ultraviolet lamp stick 3, and the light penetration ability at the peak value can be maintained for a long time.

[0039] Example 2

[0040] See also Figure 1-6In this embodiment, a tap water ultraviolet sterilization device is proposed. The cup 11 is provided with a cup cavity and a plurality of light rod cavities arranged around the cup cavity at the cup 11.

[0041] Accordingly, along the arrangement direction of the lamp rod cavity, the ultraviolet lamp rod 3 is inserted into the lamp rod cavity to slide with the sleeve cup 11 ; in addition, the shunt tube is inserted into the cup cavity to slide with the sleeve cup 11 .

[0042] To further explain, in this example, the diverter tube includes a first tube 1 and a second tube 8 combined with the first tube 1 to form a straight tube, wherein a base 10 is provided at the bottom of the second tube 8 (the base 10 is a fixing part of the ultraviolet lamp rod 3, and is used to make the ultraviolet lamp rod 3 and the diverter tube move relative to the sleeve cup 11 when the diverter tube diverts water). Accordingly, the second tube 8 is limited to one port combined with the first tube 1. In addition, a plurality of diverter holes 14 are arranged in an array on the second tube 8, and each diverter hole 14 is directly facing the ultraviolet lamp rod 3 when exposed to the outside, so that when the diverter tube extends outward from the cup cavity, the water discharged from the diverter hole 14 directly hits the ultraviolet lamp rod 3 and flows along the shape of the ultraviolet lamp rod 3.

[0043] Of course, the combination of the shunt pipe and the sleeve cup 11 requires corresponding components to be connected. For this purpose, a spring 7 is provided, and the ends of the spring 7 are respectively fixed to the sleeve cup 11 and the base 10.

[0044] See also Figure 1-6 , different from Example 1, in this embodiment, a sleeve 12 is provided opposite to the base 10 and looped around the ultraviolet lamp stick 3, the sleeve 12 extends into the lamp stick cavity and is rotatably connected to the sleeve cup 11, and the extended end of the sleeve 12 is provided with an elastic soft rod (not marked in the figure) combined with the sleeve cup 11, which is used to accumulate torque by the elastic soft rod when the sleeve 12 rotates relative to the sleeve cup 11. In addition, a soft rod 5 is provided. The soft rod 5 is looped around the sleeve 12 and extends outward to be connected to the base 10, so that the sleeve 12 rotates relative to the sleeve cup 11 when the shunt tube moves relative to the sleeve cup 11. Further, a limit ring 13 is installed at the end of the sleeve 12 to prevent the soft rod 5 from being detached after being wrapped.

[0045] It should be noted that, in this embodiment, the ultraviolet lamp rod 3 is rotatably arranged on the base 10. In addition, a plurality of contacts (the contacts are made of a soft and elastic material) are provided in the sleeve 12, and each contact contacts the ultraviolet lamp rod 3, so that when the sleeve 12 rotates relative to the sleeve cup 11, the ultraviolet lamp rod 3 rotates relative to the base 10.

[0046] Compared with Example 1, this embodiment further expands the movement mode of the ultraviolet lamp stick 3, that is, the ultraviolet lamp stick 3 can not only move up and down relative to the sleeve cup 11, but also rotate relative to the sleeve cup 11. It should be noted that the up and down movement and the rotation are performed synchronously, thereby expanding the cleaning mode of the ultraviolet lamp stick 3 to obtain a better self-cleaning effect of the ultraviolet lamp stick 3.

[0047] See also Figure 5 In both Example 1 and Example 2, a brush sleeve buckle groove 16 is provided at the end of the lamp stick cavity away from the sleeve 12, and the brush sleeve buckle groove 16 is buckled with a brush sleeve 15 of the ultraviolet lamp stick 3, so that the brush sleeve 15 can be used to clean the ultraviolet lamp stick 3 when the ultraviolet lamp stick 3 moves relative to the brush sleeve 15.

[0048] See also Figure 1-4 In both Example 1 and Example 2, a plurality of spring slots 6 and grooves 9 are arrayed at the sleeve cup 11 and the base 10, the same number as the springs 7, wherein the cross-sections of the spring slots 6 and the grooves 9 coincide, so that the springs 7 are placed in the spring slots 6 and the grooves 9 to connect the sleeve cup 11 and the base 10. In addition, a through hole 4 connected to the spring slot 6 is provided at the sleeve cup 11. The through hole 4 is an insertion channel for the soft rod 5, which is used to constrain the soft rod 5 to pass through the spring 7 and be fixed to the base 10 after the soft rod 5 is inserted through the through hole 4.

[0049] See also Figure 1-2 In both Example 1 and Example 2, a contact 2 is installed at one end of the ultraviolet lamp rod 3 to connect to electricity.

Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
